I actually prefer the Linux kernel's software RAID over controllers
these days. The data is stored in a non-proprietary on disk format, so
one isn't as the mercy of the controller if something goes horribly
wrong. I've even found the performance to be better than the cheaper
hardware SCSI RAID cards on the market.
If you are looking for performance on the cheap, four 80 GB SATA drives
running under Linux's RAID 5 driver should really impress.
